In the past days I have worked on improving the terrain generation function. The basic 3D perlin noise works well to generate a generic terrain, but to get more appealing mountains, different approaches are necessary. For height maps, perlin noise can be used too, but does not look as appealing as erosion based terrain. To achieve similar looking structures, Diffusion-limited_aggregation (DLA) is the solution. The initial result looks as the upper left image. Using gaussian smoothing, the…
